Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Sorry, wrong expression. You have a 64bit system, so do I. You can also use the 64bit runtime, but most bib and commands are 32bit and are not properly supported. I had read somewhere that there are problems with I2C. That's why I recommend switching to PI_SL and using the correct gpio.

I am running CODESYS V3.5 SP19 Patch 2 (64-bit) I have buttons that are supposed to be either red or green depending on status. When I am logged out the colors look right. When I am logged in and running the colors are completely different and I can't understand why.

Post by s1ack on Wago PFC200 Ethernet / IoDrvEthernet Issue? ^{CODESYS Forge talk (Post)}
It's suspected that the CPU loading is the Linux Kernal in the Wago PFC200 dealing with IGMP multicast traffic (@ 250 uSec) from inverters on site. The inverters use the ethernet network and IGMP to synchronize, the customer removed the switch that shipped with the system, and thus removed IGMP Snooping that was plug-and-play within the provided switch.

Post by imdatatas on Problem with edge gateway config mode ^{CODESYS Forge talk (Post)}
I encountered the same problem. (Windows10 x64 single language OS). As @eschwellinger mentioned, I uninstalled the latest EdgeGateway version and installed version 3.5.20.0. Now, when I right-click and select "Allow Edge Gateway...", Config mode is activated without any error or warning window and I do not need to manually type [CmpEdgeGateway] for EdgeGateway version 3.5.20.0.

Post by timvh on Reading multiple lines from csv file ^{CODESYS Forge talk (Post)}
Not sure, but maybe before you enter step 5, set i, lineindex and charIndex to 0. And the buffer variable should have a size bigger than 1 line. Additionally I think you should set bufferstart to 0 before you enter step 5. And in the OSCAT function you always point to the buffer address, but shouldn't this be (buffer + bufferstart)?

Hello, I am new to Codesys and I'm having trouble with running a python script on my Raspberry. SysProcessExecuteCommand2 gives result 25 and nothing happens. I used chmod +x and chmod 666 on my script. In terminal it's working when I'm using the same command line as in Codesys. Code in attatched screenshot. Thank You in advance.

Is there a way to have both a Public No Login Screens with Screens that do require login and File Transfer? My Idea is to have the default page be View Only with a Login Button in the Corner and then Once Logged In you can change settings and download files depending on your user group.

I don't know the root cause... But what could help to continue when it seems to hang, is stop the CODESYS (communication) Gateway. Go to the Windows SysTray, find the icon for the Gateway and then stop it and start it again. This will interrupt the connection between CODESYS and your controller.

Post by matthew on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
Hi @eschwellinger How does the persistent manager files work on v20? I would Like to upgrade my v19 as I'm still having issues. Sometimes if there is a power cut CodeSys won't load the Persistence Manager files and I have to redownload to the PLC and then copy my backup persistent files and then start the application. I hope it's a lot more robust in v20

Post by gunstr on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
Thank you very much for the quick answer! The RPi hw were delivered last week so it's probably a resent version. I found an old scrapped board (2 years or so) with a broken GPIO that I tested with the same SD card image and with that board Codeys can run for the full 2h demo period without issues. Then I went back the the new board to test the 4.17.0.0 release but the installation fails... [INFORMATION] Standard output: create and install daemon [INFORMATION] Standard output: codesyscontrol started [WARNING] Unable to detect Raspberry Pi Architecture. Setting armv6l as default, you can change this through the settings panel. [INFORMATION] Standard output: codesyscontrol stopped [ERROR] Expected exit value of command failed: expected 0, received 1 [WARNING] Error setting the Raspberry Pi Architecture [ERROR] Error installing codesyscontrol Do you have any idea what could be the reason? I'm using an OS image including Python drivers for LCD and some I/O:s from last year to keep things stable, but also after upgrading with sudo apt update && sudo apt upgrade I still get the same error Reverting back to 4.15.00 works fine: [INFORMATION] Standard output: create and install daemon [INFORMATION] Standard output: codesysedge started [INFORMATION] Successfully installed codesyscontrol [INFORMATION] Successfully started CODESYS Edge Gateway for Linux [INFORMATION] Successfully started CODESYS Control for Raspberry Pi SL but as before the Codesys services stops after 30 seconds. And I noticed that the Codesys control stops and is not reachable also if I have no application loaded.

Post by simone on Cannot connect to webvisu on localhost ^{CODESYS Forge talk (Post)}
As I wrote before on the title, I have difficulties to connect to see webvisu from localhost. The story: while waiting for the plc+hmi to arrive, I'm preparing the software, mainly the visual parts trough the control Win3 x64 (same version as the ide 3.5.20.10). The problem is that I can't see the webvisu with the installed webbrowser. I don't know if this is a problem, but I changed the port to 9001 (randomly "free") because 80, 8000, 8080, 8088, 3000 are all occupied by other projects (all on the Apache server). Is there something wrong with the config file? This is the url: localhost:9001/webvisu_app.htm and here the config file part "CmpWebServer". [CmpWebServer] ;The handling of startup/shutdown of the webserver: ;0->automatically start, shutdown only on shutdown of the runtime;1->automatically start, could be shutdown on demand ;2(default)->start/shutdown on demand;3->start on demand, shutdown only on shutdown of the runtime StartupType=0 ;The TCP port the webserver listens on WebServerPortNr=9001 LocalAddress=localhost ;LocalAdapterName=LAN-Connection LocalAdapterName=EthernetPCPLC ;LocalAdapterNameUnicode=L\00A\00N\00-\00C\00o\00n\00n\00e\00c\00t\00i\00o\00n\00 LocalAdapterNameUnicode=E\00t\00h\00e\00r\00n\00e\00t\00P\00C\00P\00L\00C\00 Thanks for all the help!

Post by timvh on Device diagnosis ( EtherCAT IO card ) ^{CODESYS Forge talk (Post)}
You can get the state by just using the name of your node (same name as in device tree): VAR etcState: IoDrvEthercatDriverLib.ETC_SLAVE_STATE; END_VAR etcState := EJ1100.wState; Alternatively, you can iterate through the device tree to get the status of all (Ethercat) nodes. See here an example (no guarantee it works, just give as suggestion): PROGRAM P_IO_State VAR CONSTANT uiMAX_NR_OF_TERMINALS : UINT := 100; END_VAR VAR // general device diagnosis // can only be used when the Device - PLC Settings - Advanced settings - enable diagnosis for devices is enabled // this will add the DED library coupler: DED.INode; terminal: DED.INode; aDeviceState: ARRAY[0..uiMAX_NR_OF_TERMINALS - 1] OF DED.DEVICE_STATE; uiTerminalCount : UINT; uiIndex : UINT; // for each terminal check if it implements device diagnostics xQueryResult: BOOL; itfDevice : DED.IDevice2; xDiagAvailable: BOOL; eError: DED.ERROR; xEverythingOK: BOOL; END_VAR uiTerminalCount := 0; // start at the top of the device tree with the first EtherCAT coupler coupler := EtherCAT_Master.FirstChildNode; WHILE coupler <> 0 DO // for each coupler that is found start at the first terminal terminal := coupler.FirstChildNode; WHILE terminal <> 0 AND uiTerminalCount < uiMAX_NR_OF_TERMINALS - 1 DO // for each terminal that is found get the status through the device diagnosis interface xQueryResult := __QUERYINTERFACE(terminal, itfDevice); IF xQueryResult THEN aDeviceState[uiTerminalCount] := itfDevice.GetDeviceState(xDiagnosisInfoAvailable => xDiagAvailable, eError => eError); uiTerminalCount := uiTerminalCount + 1; END_IF terminal := terminal.NextSiblingNode; END_WHILE coupler := coupler.NextSiblingNode; END_WHILE uiIndex := 0; xEverythingOK := TRUE; WHILE uiIndex < uiTerminalCount DO IF aDeviceState[uiIndex] <> DED.DEVICE_STATE.RUNNING THEN xEverythingOK := FALSE; EXIT; END_IF uiIndex := uiIndex + 1; END_WHILE

Post by mondinmr on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
I have found a very interesting solution using: IoConfigTaskMap IoConfigConnectorMap IoConfigChannelMap The first is the list of IO tasks. The second is the connector for each IO module in the IOMap. The third is the individual input or output on the IOMap. One of the properties of the connector is another pointer to a connector, which corresponds with the connector of the EtherCAT slave. Through this information, it is possible to understand to which EtherCAT slave an IO connectormap corresponds. I am attaching an FB that allows for the construction of an IO map and finding the pointer to the actual IOs in the IOMap based on the bitoffset.

Post by gerdkoch on Dynamic I/Os Mapping ^{CODESYS Forge talk (Post)}
Hi, I assume that you have a Pfc200 G2 or something and work with the original WAGO runtime. Then I would recommend the WagoSysDynamicIoMapping. Here in the example projects there is a PDF file for the library: https://downloadcenter.wago.com/learning-material/details/ll0w3pmdunzvem83g1 There is a global functional component in a GVL of the library. I think it's called DynKbusIoManager or something. The active terminals are registered there. Then there are filter Fb's for e.g. the first clamp with a specific article number. Everything is in the PDF.

Hi guys, Can someone inform where in a raspberry pi are stored the codesys programs? I´ve been training the use of a RPI as PLC, which works pretty well, however while both the RPI and PC (running codesys) remain connected to the same network. The question is: how to run the codesys program downloaded to the RPI as a stand alone device (disconnected from the PC)? Thanks! Kreis

Hello good morning everyone I would like to ask a question, is it possible to directly connect a device that only contains modbus RTU communication through an R-45 connector, directly to the PC? Or would you need an intermediate device to achieve communication? It would be of great help to me because I cannot achieve communication between the Codesys simulator plc and a Fuji Frenic mini VFD, please help me if anyone has had the same experience. Thank you so much

Post by timvh on CANbus issue ^{CODESYS Forge talk (Post)}
On a PC with the Control Win, this is probably related to the fact that the CAN drivers are not loaded. Go to the folder where your Control Win Configuration file is: - E.g. C:\ProgramData\CODESYS\CODESYSControlWinV3x64\E1FA7ABE - Open the CODESYSControl.cfg - Remove the semi-colon in front of the CAN driver you want to use (section ComponentManager). - Set the component ID to the next number in the list (e.g. Component.8) - Save this file and restart the Control Win.

Post by timvh on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
What maybe helps is the Visu Dialog ST demo project: https://store.codesys.com/en/visu-dialog-st.html This has an application IECOpenDialog where dialogs are opened using the VU.FbOpenDialogExtended function blocks. The fbOpenConfigurationDialog call has a reference (interface) to the "close listener" FB of which it's method is automatically called when the dialog is closed. This way you can create specific function blocks for each dialog when it is closed and do what you want with the data that might have been changed.
